Ainz Ooal Gown, Overlord

Vigilance, Deathtouch, Lifelink, Ward {3}

Imminence—At the beginning of each upkeep if Ainz Ooal Gown is in the command zone or on the battlefield, you
may pay {2}{b}. If you do, exile target permanent from a graveyard and put an assimilate counter on it. If that permanent is a creature, create an X/X black Undead
Minion token, where X is the exiled creatures power.

Ainz Ooal Gown has all activated and triggered abilities of all creatures with assimilate counters on them.
